1 | What: /sys/block/<device>/iosched/target_latency |
2 | Date: March 2012 | |
3 | contact: Tao Ma <boyu.mt@taobao.com> | |
4 | Description: | |
5 | The /sys/block/<device>/iosched/target_latency only exists | |
6 | when the user sets cfq to /sys/block/<device>/scheduler. | |
7 | It contains an estimated latency time for the cfq. cfq will | |
8 | use it to calculate the time slice used for every task. |
